Poor playback in Vegas at DVinfo.net

Benjamin Smith · January 24th, 2011, 11:34 AM

Hey there y'all

I am running the demo of Vegas 10 to edit in 3D and so far - wow - I've just edited a trailer in 3D and it's great to be able to actually watch live in 3D.

However, I find Vegas playback performance is pretty poor. As an example I just started Vegas and created a project at 1024x768 (my external display, which is a projector, has this resolution) and I brought in a single 1024x576 stereoscopic 3D Cineform AVI file. If I put the file on the timeline and play it on the external projector in 3D with nVidia 3D Vision glasses Vegas stutters a bit and can't quite keep up. If I play the 3D file in QuickTime or in FirstLight in 3D it works just fine.

I understand performance in these kind of apps is dependant on a great many variables; but is there anything simple I might be overlooking that I need to check to get Vegas to work faster. My actual edit, by the time I had graded a few shots and tweaked the 3D overall was pretty slow and had to be cached to RAM to play at all!

thanks for any advice,

/ben

Certainly try matching the project to the media resolution, rather than the display resolution. This tends to be best for preview performance.

Also, confirm you're on the latest Cineform release. I'm not currently using CF, but I understand there have been some issues with various v10 versions. This is probably worth reading up on...

Hi, just found this in the archive.

Could you please share with us how you got Nvidia 3D vision to work in Vegas 10?
Did you output from a Quadro FX card?
Thank you.
